Basic technical data apply for standard conditions in accordance with specification. The recommended minimum continuous workload is 50 % of nominal power output. The defined technical data are based on standard conditions according to DIN ISO and DIN Any deviations from the standard conditions can cause changes in the value of the thermal data and should be considered when designing the thermal circuit equipment (intercooler, forced cooling). When defining dimensions for the thermal circuit equipment, it is recommended that next to the output thermal power tolerance of ± 8%, an additional 10% reserve should be considered. Electric power ±5 %. Note: All data provided in technical specifications are based on full load of the engine unless otherwise defined with planned temperatures, use of natural gas with a calorific value of 10 kwh/nm³ and the gas methane number > 80, and considering technological development and changes. All pressure parameters should be measured with the stipulated pressure gauges (Pa, bar). Symbolic photos (noise chamber / container solution) 11
